THE WHITE WAGTAIL.
Although this bird is the Continental representative of our Pied Wagtail, there are on record many well-authenticated instances of its breeding in this country. It differs from the Pied Wagtail in being bluish or slate grey, where that bird is black, below the nape. Its nest, and the situation in which it is placed, do not differ from that of the bird just named. The eggs are also similar, but are said to be subject to greater variation in colour and markings.
THE BLUE-HEADED WAGTAIL.
The nest of this somewhat rare visitor has several times been found in Northumberland, and it has in all probability nested on many occasions elsewhere, without its identity being clearly established. The nest is made of dry grass, fine roots, and moss, lined with hair and occasionally a few feathers, and is situated on a bank or amongst grass or corn in a similar position to that of the Yellow Wagtail. The eggs number five as a rule, but six are sometimes found, of a yellowish-white ground colour, spotted, freckled, and clouded with light brown, and occasionally streaked on the larger end with fine blackish-brown lines.
MONTAGU'S HARRIER.
Although this bird rarely breeds with us now, its nest has occasionally been met with in recent years in the southern counties. The nest is placed on the ground amongst heath, fern, furze, or growing crops, and consists of a few twigs, straws, and bits of dead grass. Its eggs number from four to six, of a faint bluish-white, and are on rare occasions marked with a few light reddish-brown spots.
